Description

Product Information

The Dionex PDA-1 model is a high-resolution 1024-element photodiode array detector, distinguished by its 1-nm resolution, providing superior noise and drift performance typically available only in monochrometer-based detectors. Operating with Chromeleon software, this detector supports spectral overlays and 3-D plotting, making it ideal for detailed library searches and peak purity analyses. Designed for flexibility in both UV and Vis applications, it features a wide wavelength range of 190-800 nm and offers low noise and high light intensity via deuterium and tungsten lamps. It provides reliable and reproducible results due to its low baseline drift (< 500 AU/h) and includes built-in features for fast and accurate wavelength verification. Although used, this unit performs as intended, showcasing minor wear aligned with normal usage, confidently supporting warranty functionality. Its front-panel LEDs facilitate status monitoring, maximizing uptime.
